Comprehensive studies were performed in Wistar rats on the relations between the dietary protein quality and the function of the adrenocortical system. The authors determined: the increase in body mass, the urea and corticosteroid concentrations in the blood plasma, the GOT (EC 2.6.I.I.) and GPT (EC 2.6.I.2.) activities in the liver, the reactivity of the adrenocortical system in vitro, the ACTH content in the hypophyses and the content of corticosteroid-binding globulin in the blood plasma. In adrenalectomized and normal rats as well as in rats treated with corticosterone or cortisol, the authors determined the GPT, GOT, amino-acid aryl amidase (EC 3.4.I.2.) and tripeptidase (EC 3.4.I.3.) activities in the liver and the mucosa of the small intestine, and the total, alpha and beta-amylase activities in the small intestine.

We examined the clinical usefulness of serum tripeptide aminopeptidase (EC 3.4.11.4) activity in diagnosing liver diseases. We found that increased tripeptide aminopeptidase activity accompanied an elevation in alanine aminotransferase activity (ALT) in the sera of patients with non-cancerous liver diseases and that these enzyme activities were correlated (r = 0.826-0.972). In contrast, an increase in tripeptide aminopeptidase activity did not coincide with an elevation in ALT activity in the sera of patients with cancerous liver diseases. We also observed a correlation in acute hepatitis and in patients following transcatheter arterial embolization of hepatoma throughout their subsequent clinical courses. The difference in serum enzyme activities for cancerous and non-cancerous liver diseases seems to result from changes in enzyme activities in cancerous liver tissues. We found that the ratio of tripeptide aminopeptidase to ALT activity in hepatoma tissues (1.9) was 4 times higher than that in normal liver tissues (0.5).
